1. Help provides information about the choices available on the menu. You also can press F1 from any screen to obtain online Help. 2. Display Adapter Status lets you view the current settings (On or Off) for Unattended Mode, CD-ROM Boot, and Read Ahead. You also can select this choice to view information about BIOS Compatibility Mapping, logical drive sizes, and logical drives that are blocked or have a bad stripe. (See "Changing the RAID Parameters" on page 118 for more information.) 3. Change Adapter Host/SCSI ID lets you change the SCSI configuration ID or the SCSI transfer rate for the ServeRAID controller. You can change the ServeRAID controller host configuration ID to any 12 characters. If you are using Ultra Fast/Wide SCSI-3 drives, you can change the default SCSI transfer rate from 10 MHz to a maximum of 20 MHz. When the transfer rate is set to 20 MHz, the SCSI bus for the ServeRAID controller provides a data-transfer rate of up to 40 MB per second. In addition, this choice lets you change the number of hard disk drives in a group that will start up simultaneously, and set the start-up delay (in seconds) between groups of drives. 4. Set BIOS Compatibility Mapping lets you change the basic input/output system (BIOS) mapping from 8 GB (default setting) to 2 GB. (For your server, use the default setting.) 5. Set Channel → Bank Mapping lets you specify which direct access storage device (DASD) bank is connected to the ServeRAID controller. This mapping is critical for the correct operation of the Administrator Monitor utility program, which uses the settings to identify drives, to control power to specific drives, and to operate the SCSI LEDs. 4. Use the Up Arrow (↑) or Down Arrow (↓) key to highlight your choice; then, press Enter. 5. Press Esc to return to the Advanced Functions menu. 6. Back up the disk-array configuration information to diskette. See "Backing Up the Disk-Array Configuration" on page 126 for instructions. Changing Device States: You can use the ServeRAID Configuration program to change the state of a physical hard disk drive attached to the ServeRAID controller. To change the state of a physical hard disk drive: 1. Start the ServeRAID Configuration program (see "Starting the ServeRAID Configuration Program" on page 77). 116 Netfinity Server HMM

1. Help
provides information about the choices
available on the menu.
You also can press F1
from any screen to obtain online Help.
2. Display Adapter Status
lets you view the
current settings (On or Off) for Unattended
Mode, CD-ROM Boot, and Read Ahead.
You
also can select this choice to view information
about BIOS Compatibility Mapping, logical drive
sizes, and logical drives that are blocked or have
a bad stripe.
(See “Changing the RAID
Parameters” on page
118 for more information.)
3. Change Adapter Host/SCSI ID
lets you
change the SCSI configuration ID or the SCSI
transfer rate for the ServeRAID controller. You
can change the ServeRAID controller host
configuration ID to any 12 characters.
If you are
using Ultra Fast/Wide SCSI-3 drives, you can
change the default SCSI transfer rate from 10
MHz to a maximum of 20 MHz.
When the
transfer rate is set to 20 MHz, the SCSI bus for
the ServeRAID controller provides a
data-transfer rate of up to 40 MB per second.
In
addition, this choice lets you change the number
of hard disk drives in a group that will start up
simultaneously, and set the start-up delay (in
seconds) between groups of drives.
4. Set BIOS Compatibility Mapping
lets you
change the basic input/output system (BIOS)
mapping from 8 GB (default setting) to 2 GB.
(For your server, use the default setting.)
5. Set Channel
→
Bank Mapping
lets you
specify which direct access storage device
(DASD) bank is connected to the ServeRAID
controller.
This mapping is critical for the correct
operation of the Administrator Monitor utility
program, which uses the settings to identify
drives, to control power to specific drives, and to
operate the SCSI LEDs.
4.
Use the Up Arrow (
↑
) or Down Arrow (
↓
) key to
highlight your choice; then, press
Enter.
5.
Press
Esc
to return to the Advanced Functions menu.
6.
Back up the disk-array configuration information to
diskette.
See “Backing Up the Disk-Array
Configuration” on page
126 for instructions.
Changing Device States:
You can use the
ServeRAID Configuration program to change the state of a
physical hard disk drive attached to the ServeRAID
controller.
To change the state of a physical hard disk drive:
1.
Start the ServeRAID Configuration program (see
“Starting the ServeRAID Configuration Program” on
page 77).
